- the following relates to an offshore wind turbine comprising a lifting apparatus for operating a lift inside the tower and the transition piece of the offshore wind turbine.
- the following further relates to a method of installing a lifting apparatus in an offshore wind turbine.
- the tower of an offshore wind turbine may be equipped with a wire guided and wire driven lift system. Under special circumstances there may be the further need to extend the lift system from the tower further down into the transition piece, i.e. the component of the offshore wind turbine connecting the tower to a foundation pile.
- the current extension procedures are not optimized in terms of material costs and installation time, which also determines a considerable amount of labour costs.
- lift systems in offshore wind turbine are equipped with a plurality of heavy pulleys, around which the wires of the lift system are wrapped.
- Such pulleys are attached to a lower surface of the low voltage platform, which is present inside the tower at the bottom end thereof. From the pulleys, the wires extend up to the top face of the low voltage platform.
- pulleys are moved below to a hang-off platform provided in the transition piece. When tensioners are present, these also have to be moved from the low voltage platform of the tower to the hang-off platform in the transition piece.
- An aspect relates to provide an optimized mechanical setup for the lifting apparatus of an offshore wind turbine, which can lead to a reduction in terms of time and costs, in particular during the procedure of extending the operability of the lifting apparatus in the transition piece.
- the lifting apparatus comprises:
- embodiments of the present invention permit to use configurable brackets instead of pulleys.
- the only items which need to be handled are the tensioners.
- the tensioners are moved from the platform at the bottom end of the tower to the hang-off platform in the transition piece.
- the brackets are movable by rotation between the first operative configuration and the second retracted configuration.
- hinged flippable support brackets When hinged flippable support brackets are folded down in the second retracted configuration, they stay clear of the lift passage.
- a method of installing a lifting apparatus for operating a lift inside the tower and the transition piece of an offshore wind turbine comprises the steps of:
- the first steps of the above described method allow providing a lifting apparatus installed in the tower, which can move between the first station at the inner platform and another upper station, for example at the upper end of the tower or close to it. These may be conveniently performed during inshore harbour installations for building an assembly to be transported to the final offshore destination.
- phase of the method may further comprise the steps of providing a passage for the lift at the inner platform and a removably attachable support for opening and closing said passage.
- the removable support is attached to the inner platform for closing the passage and supporting the lift when the one or more brackets are in the first operative configuration.
- the last steps of the above described method allow to economically extending the listing apparatus in the transition piece, in particular once the assembly has reached its offshore final destination.
- This provides a lifting apparatus installed in the tower and in the transition piece, which can move between the second station at the hang-off platform and another upper station, for example the first station at the inner platform or another upper station at the upper end of the tower or close to it.
- FIG. 1 shows a schematic section of an offshore wind turbine including a tower and a transition piece
- FIG. 3 shows a partial lateral view of the lifting apparatus of FIG. 2 in a first operative configuration
- FIG. 5 shows another partial axonometric view of the lifting apparatus of FIG. 2 .
- the wind turbine 1 comprises a concentrated winding electrical generator 10 .
- the wind rotor 5 is rotationally coupled with the electrical generator 10 by means of a rotatable main shaft 9 .
- the wind rotor 5 is rotationally coupled directly with the electrical generator 10 (direct-drive generator configuration).
- a schematically depicted bearing assembly 8 is provided in order to hold in place the rotor 5 .
- the rotatable main shaft 9 extends along the rotational axis Y.
- the permanent magnet electrical generator 10 includes a stator 11 and a rotor 12 .
- the rotor 12 is radially external to the stator 11 and is rotatable with respect to the stator 11 about the rotational axis Y.
- the tower 2 includes an inner platform 20 at the bottom end of the tower 2 .
- the transition piece is attached to the bottom end of the tower 2 , below the inner platform 20 .
- the transition piece 7 comprises a hang-off platform 30 longitudinally distanced from the inner platform 20 .
- the lifting apparatus 100 operates the lift inside the tower 2 and the transition piece 7 along the longitudinal axis Z between a plurality of stations including a first station at the inner platform 20 and a second station at the hang-off platform 30 .
- FIGS. 3 to 5 show components of the lifting apparatus 100 .
- the lifting apparatus 100 comprises a plurality of wires 41 , 42 , 43 , 44 for operating the lift between the plurality of stations.
- the plurality of wires 41 , 42 , 43 , 44 (four wires 41 , 42 , 43 , 44 are shown in the attached figures) includes at least a traction wire, a security wire and a plurality of lift guiding wires.
- the lifting apparatus 100 further includes a plurality of tensioners 51 , 52 , 53 (three tensioners are shown in the attached figures) attached to at least a portion of the plurality of wires 41 , 42 , 43 , 44 .
- the tensioners 51 , 52 , 53 provide a tension to the wires 41 , 42 , 43 , 44 to which they are attached.
- bracket 60 is parallel to the longitudinal axis Z of the offshore wind turbine 1 and disposed in such a way to stay clear of the lift passage.
- the method of installing the lifting apparatus 100 comprises the further step of providing a travel cable pulley 70 for guiding at least a portion of the plurality of wires 41 , 42 , 43 , 44 , the travel cable pulley 70 being comprised between the inner platform 20 at the bottom end of the tower 2 and the bracket 60 when the bracket 60 is in the first operative configuration and the lift is at the first station.
- the pulley 70 follows the lift running at a predefined distance under the lift cabin. This makes sure that the power supply cable is moving in a controlled manner when the lift is in operation.
- the pulley 70 is therefore always intermediate between the lift and the plurality of tensioners 51 , 52 , 53 .
- At least a portion of the plurality of wires 41 , 42 , 43 , 44 is guided by rollers 71 provided on an external surface of the pulley 70 .
- the wires 41 , 42 , 43 , 44 may be guided through bushings (not shown in the attached figures).
